That’s the message from environmental scientist Dr Shanna Swan who has written a book on what pollution is doing to human reproduction.
She explains that fertility rates are falling due to the impact of a chemical used in manufacturing plastics. The chemicals, called phthalates, impact the endocrine system in humans.
Basically, it means a lot of babies are being born with noticeably smaller joysticks. Dr. Swan researched the effect by examining phthalate syndrome, which is found in rats whose fetuses were exposed to the chemical. She found they were likely to be born with shrunken genitals.
Phathalates mimic the hormone oestrogen and can disrupt the natural manufacturing of hormones inside the human frame. Researchers have connected this to interference in sexual improvement in babies and behaviours in adults. A variety of other factors are made inside the book, such as the truth a man nowadays has most effective 1/2 the wide variety of sperm his grandfather had. And global fertility has dropped greater than 50% over the past 50 years.
‘The current country of reproductive affairs can’t hold plenty longer with out threatening human survival,’ Dr Swan writes.
‘Of five viable standards for what makes a species endangered, only one desires to be met; the contemporary scenario for people meets at least three.’
